COOKING APPARATUS.

Specification of Letters Patent.

Patented Sept. 17, 1918.

` 4Application filed January 2, 1918. Serial No. 209,881. i

To all whom it may concern c Be it known that I, WILLIAM F. Roos, a citizen of the United States, and a resident of Mamaroneck, in the county of Westchester and the State of New York, have invented cert-ain newv and useful Improvements iir Cooking Apparatus, of which the following is a specification.

This invention relates to a cooking apparatus of novel construction in which the food is adapted to be parboiled, or partly roasted, fried or otherwise prepared and is then sweated in a closed chamber to complete the ing 4 between the walls.

operation. The construction of the device is such that the size of its sweating compartment may be changed, that the apparatus may be reversed, for supplyin either top or bottom heat, and that any radiation or waste of heat during the parboiling or sweating operation is prevented.

In the accompanying drawing:

Figure 1 is a vertical longitudinal section of a cooking apparatus embodying my invention; n

Fig. 2, a section, partly broken away, on line 22 Fig. 1;

Fig. 3, .a detail of the supporting flange and adjoining parts, and

Fig.4, a vertical longitudinal section of a modification.

The apparatus comprises a casing A, which is open at the top and bottom and is shown to be of oval shape, though it may be of rectangular or other configuration if desired. The casing is composedvof an outer metal wall 1, a pair of inner metal walls 2, 3 and an asbestos or similar insulatin pack-y From pac ing 4, there extends inwardly a flange or support 5, which divides the interior of the casing into anupper compartment and a lower .compartment, the flange being so positioned that one of said compartments is considerably higher than the other. With the embodiment shown, the flange extends from the packing, a distance above the center thereof, so that the lheight of the upper compartment is correspondingly less than the height of the lower compartment. n The walls 2 and 3 are provided at their contiguous ends with inwardl projecting flanges 6, and 7 which respective y overlie and underlie flange 5, so as to reinforce the latter. Upon upper flange 6, is supported a grate 8, while a similar grate 9, may underlie lower flange 7 the two grates if used, being connected by adapted vshell 20, inner metal bolts 10 passing through flanges 6, 5 and 7. If desired, however, a top grate only need be used, which is removed and replaced, when the casing is reversed, as hereinafter more fully referred to. It will be seen that by the construction described, the inner walls, 2, 3 as well as the grates 8, 9 are insulated by the packing 4' from the outer wall l, so that heat is not transmitted to the latter. Between the grates (or opposite to flange 5) there is formed a chamber which is interposed between the upper and lower compartments and is designed for the reception' of a heating' element. l The latter is preferably formed of van electric resistance coil 11, threaded through a bead 12, that extends inwardly from flange 5, the coil being connected by a plug 13, to the leading in wires. If desired, however, the electric heat Y element described may be replaced by gas burners or other heat generators.

, The upper compartment of casing A is adapted to be engaged by a flanged lid or cover B, which is of such a size and configuration as to be snugly received within said compartment and to rest on the flange 6 of the latter. The lid is composed of an outer metal shell 14, an inner metal shell 15, and an interposed layer or packing 16 that insulates the outer shell from the kinner shell. It is also preferably furnished with vents 17, controlled by a register 18, and with handles 19. rlhe lower compartment of casin A is to receive a similar flanged id or cover C, which is adapted to abut against so f flange 7, and is formed of an outer metali.

shell 21, and an interposed insulating packing 22. Thisl lid C is likewise furnished withk vents 23, a register 24 and handles 25. f v

While the lids B and C are similar in construction and configuration, they are different-in height, the height of the upper lid correspondin to thatk of the upper com artment, whi e the height of the lower li cor- In this way, each lidv is adapted to com pletely fill out the compartment within which it is nested, and within which it is reversible.

In use, the food is placed in a cooking utensil 26 which is introduced either into the upper or the lower compartment, and such compartment' is then closed by its lid, while the lid of the inert compartment is reversed, so that in this way, the head of the reversed responds to that of the lower compartment.

lid forms a partition across casing A that cuts ott the heat from said inert compartment, and prevents waste. Thus if a smaller cooking utensil is used, it is placed in the smaller compartment and the larger lid is reversed, while a larger utensil is placed in the larger compartment with the smaller lid reversed, but of course, both compartments may be used simultaneously. After the utensil has been introd-uced, the current is turned on Vto parboil the food, and then the heat is turned ott', and the food is allowed to sweat, within its lid until done to the extent desired.

The apparatus permits of a variety of adjustments which will readily suggest themselves: Thus, for instance, the apparatus may be reversed to carry either compartment to the top, and permit either top heat or bottom heat to be applied to either compartment; the larger lid may be fitted to the smaller compartment, to increase the aggregate height of the heating Chamber formed thereby, and the smaller lid may be fitted into and partly drawn out of the larger compartment, so as to here likewise form a larger heating chamber.

With the embodiment shown in Fig. 4, the supporting fiange 5 of the packing 4, is

located so near the top of the casing A, that the upper compartment is ractically eliminated and replaced by a gangs 27. With this construction, the casing is likewise reversible, so as to obtain either top or bottom heat, while the two lids D Iand E are adapted to be nested within the' single heating chamber. Either lid may be so mounted on the top of the casing, that an additional upperhe'ating chamber is formed thereby (dotted lines Fig. 4) or the upper lid may vbe reversed, to yrevent an upward radiation of heat when t e lower compartment is utiiized.

I claim;

1. A cooking apparatus, comprisinga casing which is open at both ends and has.an upper compartment, a lower compartment, and an -intermediate heatin element, com'-y bined with a flanged reversile cover adapted to be received by either ofsaid compartments.v l

2. A cooking apparatus comprisinga casing which is open at both ends and has an upper compartment, alower compartment, one of said compartments being of greater height than the other compartment, and a ments.

heating element intermediate said compartments, combined with a pair'of reversible `covers adapted to be respectively received by said compartments, one of said covers being of greater height than the other cover.

3. A cooking apparatus comprising a casing which is open at both ends and has an inwardly extending support that divides said casing into an upper compartment and a lower compartment, a hcatinor element carried by said support, and a palr of reversible covers adapted to be received by said compartments.
